Actor Allusion: Buddha Bob is the good-natured janitor who also gets to be the boys' mentor figure time by time. With a proper haircut and shave, he will remind anyone of another janitor from Polk Middle School.
In "Big Time Wedding", the man from immigration headquarters removes his glasses in a familiar fashion (like a certain Vice Principal...) He even persecutes the same janitor character like he did in their previous show.
In "Big Time Video", Marcos the photographer berates the boys that their video was horrible, saying "My dead chihuahua could do better!" Carlos Alazraqui (who plays Marcos) voiced the Taco Bell chihuahua that died in 2009. The episode aired mid-2010.
In "Big Time Cartoon", Daran Norris, who portrays Buddha Bob also portrayed Cosmo in The Fairly Oddparents. When Buddha Bob is hit and starts thinking he's Cosmo, he slips into the voice he uses for Cosmo.
The Other Darrin: Spencer Locke was replaced by Kelli Goss as Jennifer 2 (the blonde one) when the former was filming Resident Evil: Afterlife. While Locke whould return for the Jennifer role and Goss gets another background character role, the positions were reversed for the second half of Season 2.
Screwed by the Network: Nickelodeon's ratings during the end of 2011 were declining, pulling this show's ratings down because of their inconsistent scheduling. Fans were expecting the third season to be their final season; it was a surprise when it was renewed for a fourth season.
There is a perception that Nickelodeon is neglecting the show and the band to focus on One Direction, angering both BTR fans and One Direction fans. Although the Nick-1D relationship never really went anywhere, BTR still was on the losing side because the British boy band would go on to become far more popular than their American counterparts.
What Could Have Been/The Other Marty/The Pete Best: Kendall wasn't originally a character in the show, instead another character Curt, played by Curt Hansen (who would later go on to play a parody of Zac Efron on the show, Dak Zevon), was the lead singer and protagonist of the show. Hansen only appeared as "Curt" in the unaired pilot. Then he was later replaced by Kendall Schmidt, because he (Hansen) sounded too much like James, looked a bit too old, and didn't "click" as well with the other three, so the pilot was reshot.
